Diamond Machining Technology (DMT) Diafold Serrated Diamond Knife Sharpener, Fine (FSKF), 4"

I have this Diafold "Serrated" Knife sharpener in the Fine and Coarse diamond grits, and has thus far been very impressed with the quality of these sharpeners.I originally bought this with just the task of sharpening serrated knife edges in mind, but this sharpener has turned out to be more than just that. First, for the serrated edges - I have two Sypderco knives (Police, Delica) that have a combo serrated edge, and between this and the coarse grit, it works very well on re-honing the edge on the serrated VG-10 edges. Due to the VG-10 being a little more difficult to sharpen, your method has to be steady and you have to stick with it on the fine grit to get a nice edge.For the serrated knives in the kitchen - most of my kitchen knives are much softer and easier to sharpen than the Spyderco serrated edge - so after sharpening the Spyderco's the kitchen knives were a breeze. I used the coarse to get the edge started, then moved to this fine grit to finish it off.Where this sharpener came in handy and as a surprise is when I discovered how well this works on my small pen knives, pocket knives and mostly woodshop tools. It is perfect for pen knives and small pocket knives for touching up an edge - the size of the rounded rod is perfect for control and for small edges. Also, in my woodshop I use exactor knives and other carving / cutting tools that have curved edges For instance, Lee Valley makes a small carving tool with replaceable blades of different shapes / contours - like curved, sloped, straight blades - and these Diafold rod sharpeners turned out to be PERFECT for this application. I have also employed this tool in some of my plane restoration projects when there are tight spots that need a little filing or honing.The uses for this tool seem to increase daily. For instance,I wanted to touch up the edges on my electric hedge trimmer - again, tight spots without a lot of clearance and small edges to sharpen on the hedge trimmer - and this tool again shone in that application.Nice tool, highly recommended if you have any applications like serrated, tight spots, small edges, etc. I own many DMT tools, and the quality does not need to be justified - that is one thing you can rest assured of, that the quality is there.Thanks for reading.

If you're like me, you read all the recent reviews (I give no credence to old reviews, regardless of Amazon sorting). This thing is awesome for sharpening serrated knives. I want to dispute some things negative reviews have stated. The handles are easy to open on the ones I received. And who cares - if you don't like it, send it back. The other main complaint from people is the diamonds rubbing off. It's possible there was some bad plating at one time, but not now. If you use it correctly, with essentially no pressure (never use pressure with diamonds), follow the instructions (read them!), or look at other websites that explain in much more detail, you will have no problems. Diamonds are so different than other sharpening methods that you have to discount reviews from people who haven't used them before, even if they claim to be experienced - they may not be experienced with diamonds. They work. Use as directed. I do hate the handles and would gladly pay double for nice ergonomic (not even retractable) handles. A nice round wooden handle would be better. I can't ding a star because of the lousy handles because the price is right for what you get, as it is. I'm sharpening Cutco serrated knives which have this ridiculous "D" serration. All that does is try to ensure you use them for sharpening (and buying more knives). Even the micro-serration on the cheese knife is no problem for this sharpener. Multi-level marketing at its worst. They are great knives, but go ahead and sharpen them yourself. Re-profile them with these DMT sharpeners. It takes very little work to fix them up. Use diamond plates for the non-serrated knives. We love our Cutco knives, but have now resorted to sharpening them ourselves. Definitely do not use the Cutco sharpener. That is a total waste of money.

The product works as advertised and is easy to use. I do not like the cheap plastic handles. I would pay more for a more rigid build.

Update 2/1/17: I The one I received broke on the second use. I called DMT and they sent me a new one, priority mail. They stood behind their product with absolutely no hassles. Even though the first one broke, because of this they still get 5 Stars from me.Update 1/23/17: I recently ordered another one because I lost the first one. Can't really function in my sharpening world without it.I sharpen knives, scissors and garden tools for supplemental retirement hobby income. This tool lets me get into tight spots without having to disassemble garden shears and such. Great for rounded edges that need sharpening and tight spots.Updated 5/3/2017. Ok, so I put too much pressure on it and broke it at the handle. Called the company and they told me they would send a couple of handles as I did this to another one also. Didn't receive anything for abut 10 days....started thinking about it, and in the mail today arrived two new complete of these tapered sharpeners, along with a folding flat file (fine) marked demo.If I had to reduce my tools to a small carry bag, you can be sure this would be in it. If I had to reduce to just one tool in my arsenal, this would be in the final three.

Up until recently, I have been sending out my serrated knives to a service when they needed sharpening. I got the fine diamond blade which is all you will really need if your serrated knives are not too dull to start with and it will get your blades back to factory sharp in short order. It is easy to use and works on serrated knives as well as scissors, vegetable peelers and the like. Do not be surprised by the size or the price, this tool is serious and will give you years of solid use.

Was good for a couple years but the diamond coating gradually wears off.
